I think world of tanks is what fried my last computer. I installed it, it crashed on me 3 times (tried it twice then again with graphics on min) and the computer wouldn't boot up again consistently after, I managed to get it back to windows after a system restore but then it bricked on me after a reboot.
I had the orange box for xbox and tf2 never really interested me, it was ok with mates but it still didn't have the depth to keep me involved for very long.
Also as I've not gamed on PC in years, I'm basically playing solo for a while until I make some new friends. I'd be tempted to pick up games like borderlands otherwise, but I didn't find it as good solo.
